To (LIZ 'Uilm/11l it 'ln/(ty ron/cern,.-

Be it known that I, JOHN C. Bnciirmnn, a citizen of the United States,and a resident of Pittsburg', in the county of Allegheny and State ofPennsylvania, have invented a certain new and useful Improvement inGas-Burners for Furnaces, of which the following is a specification.

My invention relates to fuel-gas burners for furnaces; and my object isto producea burner having a 'cries of burners connected to a commonsource of gas-supply, the burners being' provided with independent meansto mix the air and gas and so disposed with relation to a shield abovethe same as to throw the iiame outward therefrom and cause the air toascend up through the space between the burners and the shield to therear of the iiame to prevent as much as possible the passage of cold airup the walls of the furnace; and to these purposes my invention consistsin the novel construction and arrangement of parts hereinafter set forthand described, reference being' had to the accompanying' drawings,forming part hereof, in which- Figure l indicates a plan view of my im-Fig'. 2 is an elevation of the same. Fig. 3 is a section taken on theline 3 3 of Fig'. 1.

Referring to said drawings, l is an annular base or support, the upperedge of which is provided with an outwardly-projecting iiange '0, whichserves as a shield or guide to project the flame from the burners towardthe walls of the furnace, and an inwardly-inclined top which is boltedor otherwise suitably secured to the gas reservoir or chamber 2, bothhaving' lugs c, which are provided with bolt-orifices for the receptionof the bolts Z to admit of this. The said annular support is preferablyformed in two parts or sections, the divisional line of which issection-line 3 3 of Fig. l, to enable the same to be quickly and readilyplaced in the furnace through the door thereof. The said reservoir 2, onthe lower side or bottom thereof, is provided with a centrally-disposedboss e, which is screwthreaded for the reception of the uppercorrespondingly-threaded end of the gas-supply pipe 3. 4 4 are series ofradially-disposed gas-discharge pipes constituting' burners, the innerends of which are screw-threaded and connected to and communicate withthe interior of the gas reservoir or chamber 2 and are each providedwith an orificef', slightly in advance of the point at which said pipesare connected with the gas-reservoir, whereby air is admitted to each ofsaid burners and caused to mix with the gas prior to its emissionthrough the small perforations g, formed around the periphery of theared or bellshaped outer end of the said gas-discharge pipes, at whichpoint it is ignited. The said annular base or support has formed thereina number of V-shaped openings it, extending from the lower edge thereofto a point slightly above or on the same horizontal plane with the topof said g'as reservoir or chamber. The gas-discharge pipes project insaid openings, the iiared outer end of said pipes terminatingapproximately on a vertical plane with the periphery or outer edge ofthe shield of the circular base, forming' a contracted space above andto the rear ofthe burners, the shield forming a guide or deflectingplate, which causes the iiames from the burners to be projected towardand against the walls of the furnace and thereby limit the volume of airor prevent the passage of the same upward against the walls of thefurnace between said walls and the burners and at the same time causingthe air to pass to the rear of the flame below the shield. The spacebetween the burners forms legs y', upon which said annular support restswhen placed within the furnace.

The said burner when arranged for use is placed in such wise in thefurnace that the edges of the shield and the outer'ends of the burnersare in close proximity with the walls of the furnace, forming a verynarrow or contracted space between the burner and the said walls. Aring' m, preferably of asbestos board, upon which said support rests, isarranged upon the grate a adjacent to the walls and in close contacttherewith, forminga barrier to the passage of air up through the spacebetween the face of the burners and the walls and causes the airadmitted below the burner to pass to the rear of and above the burners,and thus largely minimizing the volume of cold air that may possiblycome in contact with the walls of the furnace. What I claim, and desireto secure by Letters Patent, is-

l. In a fuel-gas appliance for furnaces, the combination of a furnace, agas-chamber therein, a gas-supply pipe connected thereto, a series ofindependent horizontally disposed burners communicating' therewith, thesaid chamber having a horizontally-disposed lip or liange constituting acontinuous projection above said burners and terminating a short Ioo IIO

and having` a number of' openings in the sides i thereof, a circularcentrally-disposed gas-reservoir connect-ed to said annular support provided with a gas-supply pipe, a series of ra' dially-disposedgas-discharge pipes connected with said gas-reservoir the outer ends olwhich terminate in a semispherieal chamber the periphery ofI which isprovided with numerous minute pei-f'oi'ations, and means to supply airto each ot said gas-discharge pipes independently, substantially as setiorth.

3. ln a'f'uel-gas appliance Vf'or furnaces, the combination of' afurnace, a gas-chamber therein, a gas-supply pipe connected thereto. aseries ofl independent horizontally disposed burners communicatingtherewith, provided with independent mixers, and a support connected tosaid chamber, the upper edge ot' which is provided with a lip or flangeterminating a short distance vfrom the walls of' said Vfurnace andconstituting a continuous projection above said burners and forming acontracted opening above the burners between said 'flange and theburners and between the walls of said furnace and flange, whereby theair is caused to travel to the rear of` said burners vthrough the spaceor opening' above said burners. Y

4C. A fuel-gas burner comprising a centrallydisposed gas reservoir orchamber, a series of gas-discharge pi pes connected to and communieatingwith said reservoir, an annular base or support for said gas reservoirand burners, the upper edge of which is provided with a flange or shieldprojecting outwardly above the burners, means to admit air to each ofsaid gas-discharge pipes, means to supply gas to said reservoir, incombination with a ring arranged below and supporting said annular baseand in close proximity with the walls of the furnace, substantially asset forth.

ln testimony whereofl l have hereunto set my signature in the presenceof two subscribing witnesses.
